Yes—if the paper is within the XP-970’s supported paper size range, you can usually print square sizes like 8x8 or 10x10 by creating a custom paper size in the print driver or photo printing software. In the print dialog, look for paper size or printer properties, then choose a user-defined/custom size and enter the dimensions. You’ll also want to set the correct paper type and choose borderless only if that size/media combination is supported. If a size isn’t available in one tray, try the rear/manual feed if your printer supports that paper path for photo media. Also make sure your image file is cropped to a square aspect ratio, otherwise the printer software may crop or add borders.
